BUTTON FOR SUCTION-CUPS.

To all whom it may concern.'

Be it known that I, HARRY R. PRiEsT, citizen of the United States,residing at Loudonville, in the county of Ashland and State of Ohio,have invented certain new and useful Improvements in Buttons forSuction-Cups, of which the following is a specification.

This invention relates to the art of inechanical dentistry, andparticularly to artificial dentures, and the invention has for itsobject a simple, and improved construction of button for holding asuction cup to a denture, and the invention consists in certainarrangements and combinations of the parts that I shall hereinafterfully describe and claim.

For a full understanding of the invention, reference is to be had to thefollowing description and accompanying drawings in which:l

Figure 1 is a perspective view of a denture provided with a suction cup,the device emodying my invention; Fig. 2 is a transverse sectional viewthereof; Fig. 3 is a fragmentary sectional view on an enlarged scale;and, Fig. 4 is a detail perspective view of a suction cup, the cup andbutton detached.

Corresponding and like parts are referred to in the followingdescription and indicated in allv the views of the accompanying drawingsby the saine reference characters.

Referring to the drawing, the numeral 1 designates an artificial dentureor plate, that for an upper set of artificial teeth being illustrated inthe drawing, although it is to be understood that my invention isequally ap licable to lower dentures. The plate 1 is ormed with a recess2 for the reception of the button and suction cup, and the button in thepresent invention is composed of a single piece of aluminum or somesimilar light and ductile metal which is so stamped and shaped as toproduce an annular outstanding flange 3 designed to be partiallyembedded and vulcanized in the plate as clearly illustrated in thedrawing, said flange being formed with any desired number of openin s ora ertures through which the vulcanized rub er or the like passes inorder Specification of Letters Patent.

to assist in securely holding the button in place. The button is alsoformed with an integral upstanding neck 5 and a disk-like head 6, thelatter being preferably formed with a central depression as shown.

S designates the rubber cu which is formed with a central hole by w iichit may be stretched over the head 5 and secured to the neck 5 of thebutton.

In the manufacture of artificial dentures, it is customary to secure therubber disk by a pin or rivet com rising end pieces one of which isvulcanizec in the denture and connected to the other end piece by arivet, the button being thereby composed of three distinct parts. Thismethod of manufacture is not only ex ensive, and time consuming, but itis disa vantageous in that the rivet or some of the other parts areliable to be lost or misplaced. I therefore do not claim such priorstructures, but a button which is composed of a single iece or integralstructure, as illustrated in t ie accompanying drawing and described inthe foregoing specification, the button being capable of being easilyvulcanized in the plate and being securely held in place therein afterthe plate has been completed.

Having thus described the invention, what is claimed as new is:

In a dental plate securing device, the combination of a plate formedwith a recess, of a button having an integral outstanding perforatedflange, and a neck piece, and a disk-like head slightly spaced from theflange, the said flange being embedded in the plate at the recessthereof, and the material of which the plate is formed passing throughthe apertures or perforations of the flange, so as to securely bind thefiange therein, and a suction cup secured on the neck of the button andretained therein by the head of the button as and for the purpose setforth.

In testimony whereof I affix my signature in presence of two witnesses.

HARRY R. PRIEST.
